Determination Functional Theory Investigation of Polyphenolic Compounds Reactions: NMR study
Over the past decade, the chemical behavior of flavonoids as antioxidants has become the subject ofintense experimental research. In this paper, we use a quantum-chemical approach to shed light on thereactivity of four poly phenols, Benzoic acid, vanilic acid, gallic acid and flavone . In order to establishthe most efficient theoretical methodology, different methods, either Hartree—Fock-based ...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
زیست شناسی سرخرطومی طبق خارلته Rhinocyllus conicus Fröl. 1792 (Col.: Curculionidae) عامل مهار زیستی علف هرز خارلته Cirsium vulgare (Savi.) Ten. (Asteraceae) در منطقه ی ارومیه
چکیده علف هرز خارلته،Cirsium vulgare (Savi.) Ten. 1835 ، گیاهی است دو ساله که باعث بروزمشکلات جدی در مراتع و مزارع میشود. در این پژوهش، زیستشناسی سرخرطومی طبق خارلتهRhincyllus conicus Fröl, ، به عنوان یک عامل مهار زیستی این علفهرز، در منطقهی ارومیه مطالعه شد. نتایج نشان داد که این سرخرطومی دارای یک نسل در سال بوده و به صورت حشرهی کامل زمستانگذرانی میکند. حشرات کامل در اوایل خرداد ماه ...

متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
